Vontar X4 (S905X4): install to eMMC?

fwiw: following Vontar X4 specific sc2_s905x4_vontar_x4.dts seems to do well

(Makefile needs update as well)

#include "sc2_s905x4_4g_1gbit.dts"

/ {
	model = "Vontar X4";

	coreelec-dt-id = "sc2_s905x4_vontar_x4";

	auge_sound {
		avout_mute-gpios = <&gpio GPIOD_2 GPIO_ACTIVE_HIGH>;

		aml-audio-card,dai-link@1 {
			codec {
				sound-dai = <&amlogic_codec>;
			};
		};
	};
};
